HARVESTER ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application filed September 17, 1913. Serial No. 790,269.

To all whom it may concern:

Be it known that we, JAMns ANTHONY DICKEL and CHARLES HIRAM BAKER, citi- Zens of the United States of America, residing at Ottumwa, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements in Harvester Attachments, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improved attachment for mowing machines and comprises a device for connecting the driveshaft with the cutting blade.

Another object of the invention is to provide a connection with an improved type of housing with which the pivoted link is connected.

Still another object of the invention is to so construct the housing that it will be firmly connected with the frame of the cutting machine.

lVith these and other objectsin view, this invention consists of certain novel constructions, combinations and arrangements of parts, as will be hereinafter fully described and claimed.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of a portion of the frame of a mowing machine provided with the improved attachment. Fig. 2 is an elevation of the attachment showing the same connected with the shoe of a sickle-bar. Fig. 3 is a perspective view of the attachment. Fig. A is a longitudinal sectional view through the attachment. Fig. 5 is a view in elevation, looking from the opposite side of the attachment from that shown in Fig. 2.

This invention comprises a housing having the upper wall 10, from which there extends a substantially triangular side wall 11, which has a perforated block 12, formed near the top of its inner face. The upper wall 10 is provided with a longitudinallyextending slot 13 and is provided with oppositely disposed bearings 14:, through which a pin 15 passes. A sleeve 16 extends from the opposite edge of the top wall and is provided at one end with a block 17 which is provided with an opening 18 and forms a hearing. The side wall 11 is also provided with an opening 19 positioned in alinement with the opening 18 to permit the shoe 20 to be pivotally connected with the housing by having its pivoted pin 21 pass through the openings 18 and 19. A strip 22 extends from the inner end of the sleeve 16 and is braced by a bracing web 23 which extends to the bearing 1-1. A lever arm 24 is pivotally mounted upon the pin 15 and is held in the center of the slot 13 by the bushing 25. The set-screws 26 pass through the bearings 14 and engage the pin 15 to hold the pin 15 in the bearings, thus preventing the pin from working loose.

The housing is connected with the frame indicated in general by the numeral 27 by having a rod 28 pass through the sleeve 16v and held in the desired position by the rod 29 which extends through the opening 30 formed in the block 12. The rod 28 is braced by the diagonal bar 31 extending from the frame 27 to a pointadjacent the outer end of the rod 28. The reciprocating pitman 32 has its inner end connected with the rotating disk 33 and has its outer end connected with the upper end of the lever arm 24: by means of the ball and socket oint 84. The lower end of the lever arm 2-l is connected with the link 35 by means of the primary ball and socket joint 36. Thislink is also provided with an auxiliary ball and socket joint 37 by which it is connected to the cutting blade 38. The link 35 is formed of two sections which are constructed similar to each other and which are fixedly connected to each other at their central portions, by any suitable means, such, for instance, as bolts or rivets as shown at 35 in Fig. 4. It will be seen that each end of each section is provided with a portion of a socket so that when the two sections are secured together a socket will be formed at each end of the link for receiving a ball as shown at 36 for forming a pivotal ball and socket connection. A rod 10 is connected with the strip 22 and is operated by any suitable means, such as a lever, to raise and lower the housing in order to prevent the cutting blade from striking stumps or large logs. The shoe 20 is pivotally connected by means of the pins 21 to permit the sickle-bar to be raised to a vertical position when desired or necessary. The ball and socket joint connections between the lever arm 24 and the shaft 32 and link 35 permits a very free action and will, therefore, cause the machine to run easily. By having the rod 29 extending in the position that it does the grass is prevented from becoming entangled with the lever arm and link 35, thus preventing the machine from clogging! What is claimed is:

1. An attachment for a harvester comprising an upper wall, a side wall formed upon said upper wall and depending therebelow, a sleeve formed upon the opposite side of said upper wall so as to extend substantially parallel to said side wall thereby forming a space between said side wall and sleeve to form a housing, said sleeve provided with a longitudinally extending bore, said bore adapted to receive a supporting rod from a harvester frame, said upper wall provided with a longitudinal slot, a lever arm passing through said slot and pivotally secured to said upper Wall, means for rock ing said lever arm, a link pivotally secured to the lower end of said lever arm, said link and the lower end of said lever arm being positioned between said side wall, and said sleeve, said link being adapted to be attached to a cutter bar, said link being positioned between said sleeve and said side wall for preventing a foreign object from striking the same and causing the device to become inoperative.

2. An attachment for a harvester comprising an upper wall, a side wall formed upon said upper wall, a cylindrical sleeve formed upon the opposite side edge of said upper wall, said sleeve extending parallel to said side wall, said sleeve adapted to receive tired from a harvester frame for aiding and supporting the attachment, a block formed upon the inner face of said side wall and provided with an opening, saidblock adapted to be positioned upon the end of a secondary rod whereby the opposite side of the attachment will be supported, said up per wall provided with a longitudinal slot, a lever arm passing through said slot and pivotally secured upon said upper Wall, a link pivotally secured to the lower end of said lever arm, said link adapted to operate a cutter bearing, said side wall and said sleeve constituting a guard for shielding said link and the lower end of said lever arm from being struck by a foreign object when in use.

3. An attachment for a harvester comprising an upper wall, a side wall formed integral upon said upper wall, a sleeve formed integral upon. the opposite side edge of said upper wall, said sleeve provided with a central bore adapted to engage the supporting rod of a harvester, said side wall and said sleeve being formed at a spaced distance apart, a block formed upon the lower side of said sleeve, said block and said side wall provided with registering openings, a shoe positioned below said side wall and extending transversely across their lower portion, said shoe provided with pivot portions extending upwardly between said walls, pivot members positioned Within said openings and engaging said pivot portion whereby said shoe will support the outer portion of said attachment, a lever arm pivotally secured to said upper wall and extending between said side wall and said sleeve, a link secured to said lever arm at its lower portion, said link and the lower portion of said lever arm being protected by said wall and said sleeve.

In testimony whereof we hereunto our signatures in presence of two witnesses.
